Introduction
Tibial intercondylar eminence fractures are uncommon. In a review of the literature, most authors agreed that conservative treatment was suggested for non-displaced fractures. Displaced fractures were considered an indication for surgery.
Materials and methods
Between April 2000 and November 2001, five adult displaced tibial eminence fractures were treated by arthroscopic reduction and non-absorbable suture fixation. Postoperatively, the knee was immobilized in a hinged knee brace locked in full extension with non-weight bearing for 4 weeks. Range of motion and quadriceps-strengthening exercises were started 4 weeks later. Partial weight-bearing was allowed in the following 4 weeks.
Results
The average follow-up was 24.6 months (range 18–36 months). Subjectively, there was no instability or residual pain in the knee. The patients were able to resume their normal activities. Objectively, the average Lysholm Score was 95.6 (range 93–98). The average knee range of motion was 2° to 135° (range 0°–140°). All patients had a negative Lachman’s test and no pivot shift phenomenon. All fractures showed good union according to radiological evaluation.
Conclusion
Arthroscopy-assisted screw fixation is more stable, and it allows early exercise. However, the fragment must be large enough to be fixed with a screw. Comminuted or small fragments present limitations for screw fixation techniques. We used the non-absorbable intraligmentous suture to pull down the fragment regardless of small size or comminuted status. The technique is simple and provided secure fixation without damage to the ACL insertion. A second operation is not required to remove the hardware.
